If it is not wrapped in glibmm, you can always call the C function
(namely g_mkdir_with_parents()) from within your C++ code.
Also, in Gobby, we have a function that does probably the same as
g_mkdir_with_parents (which we did not use because gobby only requires
glib 2.6):
void create_path_to(const std::string& to)
{
// Directory exists, nothing to do
if(Glib::file_test(to, Glib::FILE_TEST_IS_DIR) )
return;
// Find path to the directory to create
std::string path_to = Glib::path_get_dirname(to);
// Create this path, if it doesn't exists
create_path_to(path_to);
// Create new directory
create_directory(to.c_str() );
}
